METER.

SPECIFICATION forming part of Letters Patent No. 231,958, dated September '7, 1880,

- Application filed January 5, 1880.

To all whom it may concern:

Be it known that we, FRIEDRICH A. EINEN- KEL, of Neudorfel, near Zwiekau, and CARL O. hfilLLER, of Zwickau, Germany, have invented a new and useful Improvement in Water-Meters, which improvement is fully set forth in thefollowing specification and accompanying drawings, in which Figural is a vertical section of the watermeter embodying our invention. 'Fig. 2 is vertical sectionof a portion in line 2 2, Fig. 3. "Fig. 3 isatop view'of the interior thereof.

' Figsll, 5,;andfi are views of detached parts.

-Similar letters :of reference indicate corre- 1 sponding parts in the several figures.

Our invention consists of improvements in meters, as will be hereinafter set forth and definitely claimed.

Referring to the drawings, the conducting pipe a a enters in the box b. The flow-out of water may be regulated by the vertical cylindrical stop-cock c, which is bored round and of the same diameter as the pipe. The stopcock may be manipulated by a crank, d, or any 2' 5 other analogous means. The water flows out of the spout e, and in the meantime by the small hole 0 at the lower side of the pipe-a. The hole 0 is much smaller than the hole of the spout c, and the section of it can be regu- 0 lated and closed by the screw f. The water flowing out of the hole 0 falls in the vessel 2 of a certain capacity, and which is vertically conducted within the box I). This vessel is suspended by the chain 70 to the lever 0, which 3 5 is fixed to the horizontal shaft n. The end of the lever 0 is fitted with a spring, 1), which is represented in vertical position, the lever being horizontal. This spring touches with its edge at the upper end the corresponding end of the double-armed lever 1*, which bears atits other arm the weight g, and which is arrested in its position of repose by the support 8. The proportionality of the two arms of the leverthat is to say, the distance of the point 4 5 of gravity of the weight (1 and that of the edge of the spring 12 from the center of thelever-is such that the horizontal position of the lever r is assured until the moment when the contents of the vessel t' flow out through the small hole 0 At this moment partial equilibrium takes place. A small increase of the quantity of water inthe vessel 2 causes it to descend, that is to say, the lever 0 turns downward, the weight g is raised, the edge of the spring 1) leaves the end'of the lever 0, and the vessel t" descends without any obstacle, and as the end of the shaft n is formed as a stop-cock, the outflowot' water is prevented by the said shaft and the chain It and lever 0.

The vessel t has fitted in its bottom a heavy valve, 2?, which for better vertical movement is suspended by the cord h. The valve t closes water-tight when the vessel is in its uppermost position, so that the vessel can be filled without loss of water. The descending vessel makes the vertical way g, and rests on the bolts u a, which are titted with india-rubber disks.

In the upper position of the vessel 0; the distance g of the point of the valve and the bottom of the vessel is less than the way g. For this cause the point of the valve touches the bottom of the box I) while the vessel is yet descendin g 5 consequently the water begins toescape from the vessel by the valve t and the side holes of its seat into the box I) and flows 7 out through the pipe at. The shaft extends outside of the box 0, so that the apparatus may be remounted by a key after every descent of the vessel t, which will be indicated by the fact that although the stopcock c is opened no water will flow out of the spout of the pipe a.

In raising the vessel t by the shaft on the stop-cock at its end is reopened for the outflow of water. 8

The principle of mcas'uring.The amount of friction 2, which, besides the weight 1, is to overpower, may be determined by a direct experiment in such a way that at the momentin which the spring 1) is released from the lever r the quantity of water that successively flows down into the vessel 1' is ac-i-z gallon.

As before said, the small hole 0 can be regulated by the screw f consequently one is able to determine by direct proof what part of the water flowing out of c flows through the hole 0 into the suspended vessel 27.

Suppose the quantity of one gallon in the vessel causes the closing of the pipe a in the before-described manner, and the part of water a scale, I, is established with the pipe at, every part of which corresponds to one revolution of the lower edge of the scale l.

To apply and regulate the whole apparatus it is only necessary to note the found positionof the screw, which corresponds to the determined relation.

Within the apparatus a counter is arran ged, which notes the different descents of the vessel, so that it is possible to exactly determine the consumption in a certain time.

A spring, 0, fixed to the shaft 12, gears with a toothed wheel, 20', so that every descent of the vessel causes the advance of one tooth of the wheel w, and a pawl, w, prevents the return of the wheel 10 while the vessel is remounted.

The controller in possession of the key of the box of the apparatus has nothing more to do than to note the position of the counter, to

find the number Z of descents, and to determine the consumption as follows Z x200 gal lons. After having made this notice the coun ter is turned to its original position, 0.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In combination with suspended vesseli and pipe a, having small opening 0 which discharges into said vessel, a stop-cock which is operated by the descent of said vessel.

. 2. In combination with vessel 01 and pipe a,
